Irish Breakfast is a style of breakfast black tea. The term "Irish Breakfast" is used primarily outside of Ireland; in Ireland this style is referred to just as "tea".

Like other breakfast teas, it is often a blend, and is defined more by its character than by the particular styles and regions of origin of tea used to produce the blend. However, Irish Breakfast tends to include Assam black tea in greater proportions, giving the blend a stronger flavor, and a rich, malty character. Some Irish breakfasts are made only out of Assam. Mechanically processed CTC (Crush-Tear-Curl) teas are commonly used in this blend, as they infuse quickly and result in a bold flavor.

Irish Breakfast is similar to English Breakfast, but tends to be significantly stronger tasting. The tea is widely described with the Irish saying that tea should be "strong enough for a mouse to trot on".[1] Irish Breakfast is also similar to Ostfriesen tea, a strong black tea blend originating in Germany, which also usually features Assam tea prominently.

Overall though, this tea is very well crafted and goes well with a blanket on a cold rainy day. Being rather caffeinated, I usually have this tea on days wh...
